Genetics play a big role

One Mhehe from Iringa was admitted to a Hospital in Dar for a heart transplant. Prior to the surgery, the doctors needed to have his type of blood in store, just in case the need would arise during the course of the surgery. Apparently he had a rare type of blood, which couldn't be easily found at the hospital. A call went out to volunteers from different regions in Tanzania .

Luckily a Chagga man from Marangu had a similar type of blood. The chagga willingly donated his blood for the Hehe man. After the surgery, Mhehe sent the Chagga as appreciation, a new Toyota Prado, diamonds, lapis lazuri jewellery, and a million US dollars. The Chagga was of course delighted and amazed by Mhehe?s generosity.

It was later discovered that the surgery was not very successful and Mhehe had to go through a corrective surgery. His doctor telephoned the Chagga who was more than happy to donate his blood for the second time. All went well with the second surgery, and in order not to look so mean, Mhehe sent the Chagga a thank you card and a jar of sweets.

The Chagga was shocked to see that this time Mhehe did not reciprocate his kindness as he had anticipated.

He phoned Mhehe and said to him? I thought you?d give me expensive gifts like you did last time. But you have only given me a thank you card and a jar of sweets?.

To this the Hehe man replied 'Massawe..... I have Chagga blood in my veins now'
